GENERAL POWER TOOL SAFETY WARNINGS

WARNING: READ ALL SAFETY WARNINGS AND ALL INSTRUCTIONS. FAILURE TO FOLLOW THE WARNINGS AND INSTRUCTIONS MAY RESULT IN ELECTRIC SHOCK, FIRE AND/OR SERIOUS INJURY.
Save all warnings and instructions for future reference.
The term "power tool" in the warnings refers to your mains-operated impact wrench

WORK AREA SAFETY

1. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
2. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
3. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

1. Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce risk of electric shock.
2. Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
3. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
4. Do not abuse the cord. Never use the cord for carrying, pulling or
unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric
shock.
5. When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
6. If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

PERSONAL SAFETY

1. Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of
inattention while operating power tools may result in serious personal injury.
2. Use personal protective equipment. Always wear eye and ear protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
3. Prevent unintentional starting. Ensure the switch is in the off position before connecting to power source, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.
4. Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
5. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
6. Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
7. If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.
8. Hold power tool by insulated gripping surfaces, when performing an operation where the fastener may contact hidden wiring or its own cord. Fasteners contacting a "Live" wire may make exposed metal parts of the power tool "Live" and could give the operator an electric shock.

POWER TOOL USE AND CARE

1. Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the
rate for which it was designed.
2. Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
3. Disconnect the plug from the power source and/or the battery pack from
the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of
starting the power tool accidentally.
4
Page 5
4. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
5. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool's operation. If damaged, have the power tool repaired before use. Many
accidents are caused by poorly maintained power tools.
6. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
7. Use the power tool, accessories and tool bits etc. in accordance with these
instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those
intended could result in a hazardous situation.

IMPACT WRENCH SAFETY INSTRUCTIONS

1. Use the wrench correctly. Only use the impact wrench in the manner and for the functions described in these instructions.
2. Changing Sockets. Always disconnect the machine from the power supply
when changing sockets etc. Use only Impact Wrench sockets....DO NOT
use standard sockets.
3. Achieve the correct torque. Always finish tightening wheel nuts with a torque wrench or suitable spanner to the wheel-nut torque as recommended by the vehicle manufacturer.
4. Avoid excessive use of the wrench. When tightening a nut or bolt, never allow the wrench to impact more than 8 times - to avoid over tightening - 3 to 4 impacts is sufficient.
5. Care of the mains cable. Keep the mains cable well away from the machine and ensure an adequate electrical supply is close at hand so that the operation is not restricted by the length of the cable.
6. Use outdoor extension leads. If working outdoors, always use an approved cable extension suitable for the power rating of this tool (see specifications), the conductor size should also be at least the same size as that on the machine, or larger. When using a cable reel, always unwind the cable completely.

SERVICING

1. Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power
tool is maintained.
Please keep these instructions in a safe place for future reference.

OPERATING INSTRUCTIONS

WARNING: ALWAYS MAKE SURE THAT THE IMPACT WRENCH IS DISCONNECTED FROM THE POWER SUPPLY BEFORE CHANGING THE SOCKET.
WARNING: WHEN CHANGING DIRECTION ALWAYS MAKE SURE THAT THE IMPACT WRENCH HAS STOPPED BEFORE SWITCHING TO THE OTHER DIRECTION.
WARNING: ONLY SPECIAL SOCKETS THAT ARE DESIGNED FOR IMPACT TOOLS SHOULD BE USED WITH THIS IMPACT WRENCH. STANDARD SOCKETS MAY SHATTER.

LOOSENING A NUT

1. Remove any wheel trim, before selecting the appropriate socket and placing firmly on the square drive of the wrench.
WARNING: ENSURE THAT THE CORRECT SOCKET IS BEING USED FOR THE NUTS ON YOUR PARTICULAR VEHICLE. AN INCORRECT SOCKET SIZE IS LIKELY TO DAMAGE THE HEADS OF THE BOLTS OR NUTS.
2. With the FORWARD/NEUTRAL/REVERSE switch in the REVERSE (R) position, and holding the wrench firmly in BOTH HANDS, pull the trigger fully. The nut will be impacted repeatedly until it is loosened. IMPORTANT! Release the trigger immediately the nut begins to loosen.
3. Jack up the vehicle according to the vehicles handbook so that the wheel is clear of the ground, then proceed to fully undo the wheel nuts.

TIGHTENING A NUT

1. Start the nut by hand, ensuring it is not cross threaded, then with the appropriate socket installed on the wrench, place it on the nut.
2. With the FORWARD/NEUTRAL/REVERSE switch in the FORWARD (F) position, and holding the wrench firmly in BOTH HANDS, pull the trigger gently.
3. Run each nut up in turn until it is ‘nipped’ up only - do not tighten. When all nuts are nipped up, tighten progressively by pulling the trigger fully and allowing the action to operate for 3 to 4 impacts only to prevent overtightening.
4. ALWAYS finish tightening with a torque wrench or suitable spanner. The weight of the vehicle will need to be placed on the wheel to prevent it from rotating while the nuts are tightened. Ensure the final torque applied to the nuts meets the vehicle manufacturer’s recommendations.
